Wigan have tied brothers Joel and Sam Tomkins to new five-year contracts, as well as agreeing new deals with four other first-team regulars.
The double deal for the Tomkins, which commits them to the reigning Super League champions until 2015, effectively ends any realistic chance of either player moving to Australia or switching codes to rugby union.
“It is excellent news for the club and its fans that we have been able to secure the long-term future of both Sam and Joel,” said Wigan chairman Ian Lenagan.
“The pair played a huge part in what Wigan achieved last season and are a major part of our plans for the next five years.
“Whilst rumours suggested the inevitability that such players must move to NRL clubs or rugby union, we are delighted at their preference for rugby league, their loyalty to Wigan and their belief that in Super League they can be part of an evolving and winning England team.”
